SHASTA LAKE (KRON) — It is a rare sight in Northern California, but two mountain lions were caught on camera going for a swim.

The two giant cats were spotted at Shasta Lake, which is just north of Redding.

A father and his son witnessed the mountain lions as they swam across the lake. The pair posted videos they took on facebook, which instantly went viral.

“We see two things in the water that we had never seen before, so we stopped, turned around for a quick second, and next thing you know we see two large mountain lions swimming across the lake,” father Kevin Alexander said.

Both the father and his son agree it was an experience they will never forget.

“I was excited. I really wasn’t scared because mountain lions really can’t get out of the water when they’re swimming in the middle of the lake,” son Blake Alexander said.
